When I was at Babson College I took classes in entrepreneurship studies and worked at a start-up company.  This video with Markus Persson, creator of the game Minecraft, gives you a wonderful example of a true entrepreneur. Persson or “Notch,” as he’s known to my kids and probably yours too, created Minecraft because creating games is what he did since he was eight.  As you’ll see, being an entrepreneur is less about business plans or presentations to vulture capitalists—it’s about doing what you love to do and what you have to do. It’s why a writer writes a story or a singer writes a song. It just needs to be done. No wonder Minecraft has become a $2 billion game.
